Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of Xue Dai automatic puncturing mechanism.
Background technology
< < blood station regulations for technical operation > > (2012 editions) regulation requires with pressing aseptic technique in sterile catheter connection device or hundred grades of clean benches, plasma bags to be connected with inactivation of virus blood bag in blood-plasma virus killing (methylene blue photochemical) process.Plasma bags is with puncture pigtail, and inactivation of virus blood bag, with puncture needle, inserts puncture pigtail by puncture needle and can connect two blood bags.
In plasma bags, be connected in technique with inactivation of virus blood bag, developed country adopts conduit hot melt to connect conventionally, but hot melt connects the disposable blade of use, because expensive cost is high, in real work, seldom adopts, and most blood stations all adopt artificial puncture.Artificial puncture is that operator one holds puncture pigtail, and another hands is taken puncture needle, manually punctures.Although artificial puncture technique mature and reliable, but still there is problem and the hidden danger of the following aspects:
1, plasma bags puncture pigtail good toughness, when just having started to puncture, pin need larger power just can penetrate, once break-through, pin can promptly advance, because puncture needle is with inclined-plane, in the process that moves ahead, can produce side force, or because puncture angle is grasped bad, appearance syringe needle thorn partially causes and pierces through plasma bags, stabs the situation of operator's finger.Although the blood plasma puncturing all will, through various detections to guarantee its safety, due to window phase, can not guarantee 100% safety.Once contain high-risk or infective virus in blood plasma, operator just has the probability of infection, thereby the risk of occupational exposure is very high, and this work danger that manually punctures is higher.
2, puncture needle penetrates puncture also needs after pigtail larger trying hard to recommend to certain depth that syringe needle and puncture pigtail are closely linked, unlikely coming off in transhipment and the mobile process of blood plasma.But power and the paracentesis depth of puncture can vary with each individual, and people's paracentesis depth that strength is less is shallow, and adhesion is inadequate, likely causes syringe needle to come off, blood plasma overflows the also situation of contaminated environment of scrapping and occurs.
3, when puncture quantity is more, operator is easily tired, causes decrease in efficiency, and long period of operation causes wearing and tearing and damage to finger and finger skin.
